Are the heads the same?

Are the heads on a 1998 502 MPI the same or similiar heads that come on a 2003 HP525? Mainly the question is, will a set of the HP525 CMI "Sweeper" headers fit on my 502 MPI heads exhaust ports and mounting? I might have a line on a couple of sets of these HP525 headers and need to know if they will work on my motors before I buy them.
Thanks,
Dean

S30,
Thanks, are they both just GM iron heads? Or GM Performance heads?

Heads are DEFINITELY NOT THE SAME.

But the exhausts won't know any different. Same mounting pattern and flange angle.
